PhET Collision Lab Physics – Collision lab worksheet 5.04 PhET Collision Lab

1. Open the following simulation:

Adjust the buttons and boxes in the green box on the right of the screen so
that they match the settings shown to the right. Also click the button “More
Data”.

If the simulation above doesn’t work for you try this one:
choose the Intro Lab and click Values to show the information you need.

2. Run the simulation by clicking on the button for Play. Notice that you
can adjust the initial conditions of the two balls. Also notice that you can
slow down the collision by adjusting the time lapse slider. Try a few different scenarios.

3. Using the table below, record 6 different scenario collisions. Be sure to include trials where
spheres 1 and 2 have the same mass, where 1 and 2 have different masses, where 1 and 2 are
heading in the same direction, and where 1 and 2 are heading in the opposite direction. Note that
in the table, P of 1 stands for momentum of sphere 1, and P of B stands for momentum of sphere 2.

4. Now change the settings so that the elasticity slider is set to 0. Repeat the simulation for the
data you took above using the same values for mass and initial velocities. Fill in the table
below:
